Title: Improvements in planetary variable-speed gearing drive systems
Inventor: MOREY SIGMUND
IPC: B23Q5/14
Filed: 1953-08-01
Abstract: 746,600. External band brakes. MOREY MACHINERY CO., Inc. Aug. 1, 1953, No. 21389/53. Class 103 (1). [Also in Group XXIV] A brake band 161, for holding a reaction member of a planetary change-speed gear (see Group XXIX), is anchored at its lower end 157 to a link 156, pivoted on the casing and sustained against downward reaction by a tie-rod 167 having an adjustable nut 169 bearing on a casing lug 164. Pivoted on that lug is a lever 171, linked at 175 to the operating end of the band 161 and itself operated by rightward movement of the rod 180 of a piston in a cylinder 178, pivoted at 177 to the casing and supplied with brake-applying fluid-pressure at 276a. Another similar brake which takes reaction in reverse (Fig. 4, not shown), differs in that the lower end of the band is now the actuating end and is connected directly to one arm of a bellcrank operating lever, whilst its upper anchored end is linked to the casing and sustained against upward reaction by an adjustable screwed stop bearing on the link.

Title: An improved process for the manufacture of water-proof and insulating paper
IPC: D21H17/22
Filed: 1932-08-02
Abstract: 391,350. Insulation. KNAGGS, J., MARSDEN, J. C., and PORTALS, Ltd., Laverstoke Mills, Whitchurch, Hampshire. Aug. 2, 1932, No. 21629. [Class 36.] Paper for electric insulation is impregnated with an emulsion containing a protein together with a drying or semidrying oil, or alternatively a solution of natural or artificial resin, and is subsequently treated with a reagent which renders insoluble one or more of the ingredients of the emulsion. In an example, an emulsion consisting of poppy seed oil, mineral oil, gelatine, sodium oleate, manganese chloride or sulphate and water is used, followed by a bath of aqueous formaldehyde, containing borax which reacts with the manganese salt to form manganese borate, which accelerates the oxidation of the poppy oil. Driers may be added to the emulsion. Acetaldehyde, dichromates, aluminium salts or alums may replace the formaldehyde. In a second example an aqueous emulsion containing glycerolphthalic acid condensation products, gelatine and soap, with oil or wax if desired, is used, followed by a formaldehyde or alum bath.

Title: Improvements in or relating to methods of manufacturing magnetic ferrites
Inventor: QUANTIE CHOW
IPC: C04B35/26
Filed: 1952-09-02
Abstract: A magnetic ferrite powder, which may be magnetically soft or hard, is made by forming a solution of suitable compounds, evaporating the solvent, at a temperature near its boiling point and heating the powdered residue at a high temperature.  Suitable compounds may be dissolved in water or acid, or the solution may be formed by melting crystals.  In one example, MgCl2, 6H2O and Fe(NO3)39H2 are heated together in a glass vessel at 150 DEG  C., dried between 150 DEG  C. and 200 DEG  C. and heated at 700 DEG  C. under oxygen whereby after 2 hours magnesium ferrite of 8 microns maximum particle size is formed.  Another hour of heating at 1200 DEG  C. gives a powder with half its particles greater than 8 microns.  In other examples, cobalt ferrite is obtained by sintering at 900 DEG  C. in nitrogen the residue obtained from heating below 200 DEG  C. nitric acid in which cobalt and iron have been dissolved; nickel zinc ferrite is obtained either by firing at 1000 DEG  C. and then sintering at 1200-1400 DEG C. under oxygen the residue obtained from melting and drying a mixture of FeSO4, 7H2O, ZnSO4, 7H2O and NiSO4 7H2O, or by heating at 650 DEG  C. and sintering at 1200 DEG  C. in air the residue obtained from drying water in which nickel citrate, zinc citrate and ferric citrate have been dissolved.  The ferrite powder may be used as paint, compressed and sintered to a high permeability core, or with the use of a magnetic field to a permanent magnet.  In one example the powder is first coated with stearic acid dissolved in ether.
